Amazon is prioritizing its own AI coding tool, Kiro, over third-party options, signaling a strategic shift to control its development ecosystem.

Amazon is directing its engineers to prioritize its in-house AI coding tool, Kiro, over third-party alternatives, according to an internal memo. The company plans to stop adding new external AI development tools, aiming to strengthen its proprietary Kiro service launched in July 2025. While existing tools remain supported, the move signals a strategic shift to expand control over its development ecosystem, despite Amazon’s major investments in OpenAI and Anthropic. The directive reflects broader industry trends as tech giants seek greater oversight of AI-powered coding tools.
